Abstract
A system has pneumatic or hydropneumatic spring elements which are constructed in the form of displacement units and which are configured with a first pneumatic chamber, the volume of which changes according to the respective spring stroke, and a second pneumatic chamber having a constant volume. The two chambers can be connected to and isolated from one another by a valve arrangement. An appropriate control of the valve arrangement makes it possible to ensure that, in the reversal phase between the compression stage and extension stage of each of the spring elements, marked changes of the supporting forces occur and counteract vibrations of the sprung mass.
